CSconnected represents organisations who are directly associated with research, development, innovation and manufacturing of compound semiconductor related technologies as well as organisations along the supply chains whose products and services are enabled by compound semiconductors.The UK, and in particular, Wales, is home to a growing number of organisations and businesses that are active in this increasingly important industry sector.
Our role is to support the cluster by facilitating meaningful collaboration, strengthening connections, and ensuring the collective voice of the cluster is heard at regional, national, and international levels.
Through strategic networking, curated introductions, industry roundtables, stakeholder engagement, and coordinated promotion, we create practical opportunities for members to build partnerships, access insight, raise their profile, and contribute to the continued growth of the cluster.



We recognise that political borders are largely meaningless when we consider local collaboration. While the compound semiconductor cluster is firmly established in South Wales, there are organisations ‘around’ our political boundaries which have deeper links to the cluster. If an organisation meets two of the following four criteria, we will consider them for Connected or Core Member status, and they can participate accordingly:
It is recognised that an organisation may become eligible/ineligible if their circumstances change.
We use the official European definition of an SME which is up to 250 employees and/or £44m GBP turnover.
FE refers to a Further Education organisation, which is an institution (other than a school or university) that provides education and training after secondary school for people aged 16 and over, not for a university degree.

Core members are a smaller group of organisations representing stakeholders from within the CSconnected membership. Core members are appointed by invitation only. Status is determined through a democratic decision by the Cluster Steering Board.
To become and retain core member status you must:
Membership Renewal: Core Membership is renewed annually based on fulfilling the participation criteria.
